Abstract
In this paper the methodology for determining the performance of a digital communications system consisting of M-QAM modulation (M-ary Quadrature Amplitude Modulation) affected by a fading channel with multi-path Rayleigh slow, flat and a Gaussian noise band limited is presented by means of complex enveloped simulation technique. The results are validated with some simplified theoretical probability of error for this kind of modulations and channels. The methodology establishes a systematic procedure for finding the performance curves that characterize the communication system under non idealized conditions of channel, which allow the calculation of radio links to modern systems such as LTE (Long Term Evolution) and digital television DVB-T.
